Norwalk Roofing: Article About Roof Repair
Rooftops are exposed to the elements all day and night long. Intense heat energy from the sun combined with ultraviolet radiation and the heat emanating from the attic space may cause surface problems like bubbles and blisters to develop on the tops of asphalt shingles. Not only are these deformities unattractive, but they can also cause the shingles to split or crack, leading to premature failure of the roof. With these guidelines and professional assistance from a local Norwalk roofing service company, homeowners can determine when blistered shingles can be fixed and when they're better off getting their roofs replaced.
Bubbles are most likely to develop on faces of the roof that are exposed to full sun, especially the south and west sides. They are least likely to pop up on shaded areas.
To fix a few bubbling shingles, some supplies are needed. The homeowner should gather a pry bar, claw hammer, putty knife, heat gun, plastic tarp, roofing nails, tar, caulk and a few scrap bricks. An extension ladder and new shingles that match the roof's existing pieces will also be necessary. If the second story of a home needs to be accessed, the homeowner may also want to wear a hard hat. This project should be done during a period when the weather will be dry for several days.
A roofing contractor from Sound Renovation of Norwalk CT can answer any question you have about composite roofing or siding.
Stick the pry bar underneath the damaged shingle to remove it from its place on the roof. Use the claw hammer to pull up the nails fastening the shingle to the wooden decking. The shingles may tear as they are pulled off the roof. Scrape the old roofing tar off the underlay with the putty knife. The surface should be clean and flat.
If the shingle did not tear upon removal, warm it with the heat gun until it becomes flexible. Use several bricks to flatten the shingle. Leave the shingle covered in bricks on the rooftop overnight. Cover the work area with a tarp held in place by more bricks.
In the morning, remove the tarp and take the bricks off the flattened shingle. Put a new layer of tar onto the bare spot on the rooftop. Affix the repaired shingle to the roof with the appropriate size of roofing nails. Each nail's head should be covered with a bead of silicon caulk. If an extensive area of blistering is noticed while the homeowner or roofing technician is on the roof, a total replacement is more feasible than trying to repair every section of shingles.
